.This invention relates to a clamping band device for pouring pipe joints. 3

The-object of the invention is the production'of a clamping band device torv pouring ;5 the lead joints betweenthe bell and spigot ends of pipes: '01? different diameters. hThe second object of the invention is theprodu'ction of a clamping band device in which the hand thereof will tightly hug the-pipe hav-v ing the spigot endirrespective of any deformity therein, to avoid spilling the lead or other metal while it is being poured. The third object of the invention is the production of a clamping band devicewhich can be. easily operated and cheaply manufactured or repaired. I

In the accompanying drawings Fig. 1 rep.- rese-nts a top plan view of the improved clamping band device in its open position 520 for pouring lead joints, with a pair of pipe ends; Fig. 2' shows a front View of Fig. 1 partly in vertical axial section; Fig. 3 is a view similar to Fig. 1. with theoperating elements of the clamping band in their closed or locked position; Fig. 4 shows a section of Fig. 1 on the line 4, 1; Fig. 5 indicates an enlarged fragmentary portion of Fig. 1 partly in vertical section; Fig. 6 shows a section of Fig. 5 on the line 6, Gand Fig. 7 shows an enlarged section of Fig. 3 on the line 7, 7.

20 and its accompanying bell end is shown at 21, with the upper face of thebell at 22. The

' usual annular channel 23 between the ends of the pipes is shown with the lead joint 24.

The clamping band per se is indicated at 27 and one end thereof isshown at 28, while its other end is indicated at 29.. The said band 27 in this instance consists of a rub-a ber hose having cloth or other fabric imbedded therein. The band may consist of various flexible materials, such as hemp rope and the like, and it is made long enough to Y be adaptable for pipes that vary greatly in Adjacent to the end 28 of the said band is positioned the bracket 33 having formed therewith the heel 34 at right angles.
